A multimeter is also known by several other names. It is used to measure electrical parameters such as resistance, current and voltage. The instrument is like a combination of a conventional ohmmeter and voltmeter. The gadget can utilise either analogue or digital circuits in the measurement process. The analogue model contains a microammeter over a divided scale where all the measurements are displayed. On the other hand, the digital scale will simply have an LED display with the numbers. Here are three qualities that will make an excellent multimeter.
Check the Quantities It Can Measure
The typical multimeter can measure a number of quantities. These include voltage, current, resistance, and frequency. When checking the ability of the one you are interested in buying, check whether it can measure direct and alternating current in volts. Also, see whether it can measure in amperes, direct and alternating current. Finally, ensure that when it measures frequency, the AC measurements are accurate and specific. If the gadget you are interested in is not able to make these measurements, you are better off looking for a better one. As a bonus, you could find multimeters that measure conductance, capacitance, inductance and temperature. This one will save you the trouble of having to buy all those separate gadgets.
Check the Resolution
Analogue and digital multimeters have slightly different resolutions. The digital one is gauged in the numbers that can be displayed on the resolution, also known as the digits of resolution. For example, when they say the multimeter has a half-a-unit display, it means that it can either display a zero or a one. If you are not sure about the display specifications, it is best to observe one at work and decide whether it suits your purpose. On the other hand, the analogue multimeter has a resolution which is limited by the arm of the pointer. The analogue gadget is less recommended than the digital one because its measurements are often less accurate.
Check the Cost
Lastly, not all multimeters will cost the same. Some will cost a little more than others, but this does not mean that they will give you the best value. It is best to get a balance between the value of the gadget and the cost.
Getting the perfect multimeter to suit your needs is not hard. You just need to look for a reliable supplier and brand to supply from. Look for multimeters in shops near you.
